Bells and Whistles Replace the xmin and xmax declarations in the # Parameters section of your code with the following lines: xmin = int (input ("What is the minimum x-axis (integer) value?") ) xmax = int (input ("What is the maximum x-axis (integer) value?") ) Run the code and see what they do. We can now prompt the user of our code for information and incorporate it into our calculations. The above lines of code ask the user for the parameters that determine the coordinate axes. Asking for information regarding the calculation itself, allows us to solve any problem of this type, not just the one we were assigned for homework. Here are the lines that you need, it is up to you to install them. You will have to do a bit more than simply cut and paste. ball . pos. x = float (input ("What is the initial position?") ) x = float (input ("What is the final position?") ) v = float (input ("What is the velocity?") )
